So you can stop using unnecessary exclamation points! Yeah, like that one. Young writers just love to use exclamation points, even when they are not necessary. Here’s a hint: They are rarely necessary. Only use them on sentences that are truly exclamatory. Otherwise you sound like you are shouting all the time.
So you know when to use question and when not. Students writers often forget question marks. And sometimes they use them when they are not actually asking question. There's a big difference between saying '"You know what i mean?'' and ''You know what i mean.'' A particular type of sentences causes problems here- one i'll have to write about another time. It's a sentence that talks about a question, but doesn't actually ask a question.
